Strong opinions, weakly held

The O’Reilly Network has published an article I really need to read: Setting Up a Firewall Under OpenBSD. I bought a Sparc Classic on eBay that I’m going to use as a firewall between my home network and cable modem. I was already planning on installng OpenBSD on it, so now all I need to do is set up the firewall according to the instructions in this article.
